GUN.

Application filed November 16, 1920. Serial No. 424,555.

To all whom it may concern:

Be itknown that I, HILDING J. JoHNsoN, asubject of the Kingdom of Sweden, residing'at Salt Lake City, in the county of Salt 6 Lake and State of Utah, have invented a new and useful Gun, of which the following-is a specification.

This invention relates to signaling devices, and more particularly to a combined audible and illuminating signal adapted to frighten animals to protect crops.

The primary object of the invention is to provide adevice of this character which is operated by the explosion of gas, to cause a report.

A' further object ofthe invention is to provide means for causing the continued op- 'eration of the device, at predetermined intervals.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in thedetails of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawings Figure 1 illustrates a front elevational view of the signaling device constructed in accordance with the present invention.

Figure 2 is a sectional view taken on line 2-2 of Figure 1. V

Figure 3 is .a vertical sectional view through the body portion of the device.

Figure 4 illustrates a side elevational view of the gun partly broken away to disclose feeding mechanism, the gun being shown as mounted on a tank.

Figure 5 illustrates a plan view of the lower section,-of the device.

Referring to the drawings. in detail, the reference character 5 designates the lower section of the body portion whichv is provided with a flange 6 that has notched portions 7 ,formed at predetermined points thereon, which notched portions are designed to receive the securing bolts 8, which secure the lower section and upper section 9 together, there being provided a similar flange 10 at the base of the upper section 9.

Each of these sect-ions is provided with a semi-circular portion 11 formed in the side wall thereof, the semi-circular portions when the sections are brought into operative relation with each other, acting as a compartment for the regulating tube, to be hereinafter more fully described.

This regulating tube which is indicated by the reference character 12, is relatively long and extends substantially the entire length of the body portion, and as shown, is provided with a plurality of spaced openings, each of which communicates with a discharge pipe 13, the passage of gas through the pipe 18 being controlled by the valve members 1 1. These pipes 13 also communicate with the pipe 15 which has a right angled extremity 16 disposed adjacent to the burner 17 whereby gas passing through the right angled extremity will be ignited and caused to back-fire through the pipe 18 which is housed by the regulating tube 12.

The upper section of the body portion provides the water chamber for the burner and is provided with a regulating valve 19 for controlling the quantity of water passing from the upper section to the lower section, the lower section being however the carbide containing section, there being pro vided a circular casing 20 positioned within the lower section, which casing 20 is of a diameter less than the interior diameter of the lower section to provide a space therebetween, so that gas generated within the lower section may pass outwardly between the walls of the casing 20 and the inner walls of the lower section.

A bell-shaped extremity 21 forms a part of the pipe 18, and in this bell-shaped extremity is a burner 22, which is in communication with the interior of the lower section to permit gas to pass into the pipe 18. Formed in the pipe 18 is an opening 23 which is disposed within the regulating tube to permit the gas within the regulating tube to flow into the pipe 18.

Supported at the upper extremity of the upper section is a discharge tube indicated at 24, which discharge tube has communication with one extremity of the pipe 18, there being provided a bracket member 25 that connects the tube 24 and pipe 18 to further insure against movement of the discharge tube 24.

The bracket member 25 includes a pair of arms connected by the turn buckle 26, so that movement of the turn buckle will result in a relative movement of the discharge tube 24 to adjust the same to discharge at various angles.

On the outer extremity of the discharge tube 24 is a removable tube 27 which is connected to the discharge tube 24 as by means of the band 28 that clamps the tubes 24 and 27 together. Formed integral with the tube 27 is a chamber 29 which communicates with the tube 27 through the opening 30, the opening being of a size to permit the grenades 31 to pass therethrough. Disposed within the chamber 29 is a rotatable supporting member 32 which comprises a plurality of arms 33, between which arms are supported the grenades 31, the grenades being ball-like in formation so that the same will roll freely within the chamber 29, when the supporting member 32 is rotated.

A shaft 34 supports the member 32, and on this shaft is supported the ratchet wheel 35, there being provided an arm 36 movable on the shaft 34, which arm 36supports the pawl 37 on one end thereof, so that movement of the arm 36 results in a relative movement of the ratchet wheel 35 to cause the same to rotate a predetermined distance and discharge a grenade into the discharge tube 27.

Having connection with the arm 36 is an arm 38 which has pivotal connection with the arm 39 that has the extremity 40 thereof disposed within the tube 27 so that when the gas is back-fired within the regulating tube 12, the arms 39 will move to cause a grenade to drop into the tube 27, whereupon the expansion of gases within the tub 27 will czpuse the grenade to be forced from the tube 2 It follows that due to this back-firing of gases within the regulating tube 12, a noise is produced to frighten animals from the locality in which the device is positioned.

At the rear of the burner 17 are the reflectors 41 to reflect the light from the burners, illuminating the field in which the device is located.

The operation of the device is as follows The member 19 is operated to permit a predetermined quantity of water to drop into the casing 20 where the same contacts with the carbide positioned therein, with the result that gas is generated, which gas passes upwardly and between the casing and the inner wall of the lower section, where the same passes to the nozzle 22. From this point the gas enters the regulating tube 12 through the opening 23 formed in the pipe 18.

One of the valves 14 is now operated to set up communication between the regulating tube and pipe 15 with the result that the gas passes through the pipe 15 to the outer end thereof. It follows that when the gas contacts with the flame of the burner 17, the gas back-tires through the pipe 18 and tubes 24 and 27 to the end. that the arm 40 is moved upwardly and the impact of the back-fire is directed to the grenade 31 which has now fallen into the tube 27 The grenade is discharged from the end of the tube 27 which grenade is of the usual character to explode and cause either an illuminating or audible signal to be made.

It might be further stated that by moving predetermined valve members 14 the pi e 15 will be brought into communication wit the regulating tube 12 at various levels, with the result that the time of the explosions may be regulated. It is of course obvious that as the gas passes upwardly through pipe 18 and fills the pipe, the gas is forced through the opening 23 of the pipe 18 and fills the tube 12 from the top downwardly,

and when the gas within the tube reaches a point opposite the opened valve 14, the gas flows outwardly to the pipe 15 to accomplish the aforesaid result.

It of course takes a greater period of time for the gas to fill the tube 12 to one of the lower pipes, than it would to fill the tank from the upper end to one of the upper pipes, with the result that when the upper valve members 14 are moved to establish communication between the tube 12 and pipe 15, the back-firing will occur at shorter intervals, than if the lower valve members were turned to provide such communication.

Having thus described the invention, what is claimed as new is:-
